* Closes #4473 This PR introduce `Style::wrap_mode`, which adds support for text truncation in addition to text wrapping. This PR also update some width calculation of the ComboBox. #### Core - Add `egui::TextWrapMode` (pure enum with `Extend`, `Wrap`, `Truncate`) - Add `Style::wrap_mode: Option<tTextWrapMode>` - **DEPRECATED**: `Style::wrap`, use `Style::wrap_mode` instead. - Add `Ui::wrap_mode()` to return the wrap mode to use in the current ui. If specified in `Style`, return it. Otherwise, return `TextWrapMode::Wrap` for vertical layout and wrapping horizontal layout, and `TextWrapMode::Extend` otherwise. - **DEPRECATED**: `Ui::wrap_text()`, use `Ui::wrap_mode` instead. #### Widget - Update the width calculation of the `ComboBox` button (_not_ its popup menu). - Now, `ComboBox::width()` (defaulting to `Spacing::combo_width`) is always considered a minimum width and will extend the `Ui`, regardless of the selected text width and wrap mode. - Introduce `ComboBox::wrap_mode`, which overrides `Ui::wrap_mode` for the selected text layout. - Note: since `ComboBox` uses `ui.horizontal` internally, the default wrap mode is always `TextWrapMode::Extend`, regardless of the caller's `Ui`'s layout. - The `ComboBox` button no longer extend to `ui.available_width()` with wrapping is enabled. - **BREAKING**: `ComboBox::wrap()` no longer has a `bool` argument and is now a short-hand for `ComboBox::wrap_mode(TextWrapMode::Wrap)`. - Added `ComboBox::truncate()` as short-hand for `ComboBox::wrap_mode(TextWrapMode::Truncate)`. - Update `Label` - Add `Label::wrap_mode()` to specify the text wrap mode. - **BREAKING**: `Label::wrap()` no longer has a `bool` argument and is now a short-hand for `Label::wrap_mode(TextWrapMode::Wrap)`. - **BREAKING**: `Label::truncate()` no longer has a `bool` argument and is now a short-hand for `Label::wrap_mode(TextWrapMode::Truncate)`. - Update `Button` - Add `Button::wrap_mode()` to specify the text wrap mode. - **BREAKING**: `Button::wrap()` no longer has a `bool` argument and is now a short-hand for `Button::wrap_mode(TextWrapMode::Wrap)`. - Added `Button::truncate()` as short-hand for `Button::wrap_mode(TextWrapMode::Truncate)`. #### Low-level - **BREAKING**: `WidgetText::into_galley()` now takes an `Option<TextWrapMode>` instead of a `Option<bool>` argument. - **BREAKING**: `WidgetText::into_galley_impl(()` now takes a `TextWrapping` argument instead of `wrap: bool` and `availalbe_width: f32` arguments. --------- Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com>

In some context, it would be useful to have
ui.label(txt)defaults to truncate, such as we don't have to change them all forui.add(egui::Label::new(txt).truncate(true)). Likewise, it would be nice to have aui.label_truncated()helper (though each might be suited for different situations).As per:
